Questions & Answers about jihacheori beoseuboda deo bissayo.

What is the function of 보다 in this sentence?

보다 is the comparative particle meaning “than.” In 버스보다, it marks 버스 as the thing you’re comparing to. So 지하철이 버스보다... literally means “The subway, compared to the bus...”

Why is 더 used when 보다 already indicates a comparison?

While -보다 alone can express “than,” adding 더 (“more”) emphasizes the degree: 더 비싸요 = “is more expensive.”

• 버스보다 비싸요 = “It’s expensive than the bus.” (understood)
• 버스보다 더 비싸요 = “It’s more expensive than the bus.” (clearer, more natural)

Why do we use 지하철이 here? Could we say 지하철은 instead?

• -이/가 marks the subject (what the sentence is about).
• -은/는 marks the topic or contrast.
  You can say 지하철은 버스보다 더 비싸요, which shifts nuance to “As for the subway, it’s more expensive than the bus.” Both are correct; 지하철이 simply feels like a straightforward subject marker.

How would I invert the sentence to emphasize that the bus is cheaper?
